BALL mam.

Application filed August 6, 1924. Serial No. 780,358.,

' 16 adapted 'for many different forms of sphe'ri-' .cal bodies, itsparticular use will be in marking golf balls. The type of machine is onethat-is used in stores for identifying matter on the golf balls ofpurchasers, and is also used bydhdividfials for marking their own golfballs. The inventionparticularly relatesto a supportfor'the ball, and inconjunction with it,- a slide that includes a meansfortholding-type orother im rinting 2 ,0 means, which also functions as a ho der formanually, operating the. slide.

The invention is illustrated in the, accompanying drawings in whichFigure 1* is a side view of my improved-marker. Figure 25 2 is avcentral vertical section of the ma chine shown inFigure 1. Figure 3 isasection on 33 in Figure 1. Figure 4 is a side view of the modified formof construc tion, and Figure 5 is a perspective view of another modifiedform ofconstruction.

In Figures-1 to 3, I show a'machine having-'a frame constructed'of sideplates .-which are braced and well separated by cross pieces 11; in the.top of the machine is a slideway 12 which defines the path of travel oftheslide 13', whichis usually a materially stiff sheet Jof. metaladapted to .hold the type orfotherimprinting means, which projects fromthe bottom of the'slide as shown e614.- Thetype is held in a box likecase in 15 being clamped by end screws 16 and adjusted vertically by thescrews 17.

The type may be made in one piece as in a lino-type machine, or it canbe made from separate type as shown 'in the drawing, and ,when soconstructed the type is in contact with a jacking plate 18'. Thebox-like caswhich the ing 15 serves a double function in that it acts asa type holder and also forms a handle by means of which the slide isgrasped. The slide is propelled through the frame,

' the frame being open-ended, and the slide working. freely in it sothat it can be passed into one end of the frame and out at the otherend. To minimize the friction, I usually place a roller'19 on each sideof the frame and above where the ball is supported. In the drawing Ishow agolf ball at 20, and the ball is supported so that it can rotatefreely so that when it is marked it rotates so that it points in itsperiphery and are successively engaged by the 'type. The ball can besupported onthe sup orting rollers 21,' 'ournaled as at 22 in tiie sideplates of t e frame.

The parts are dis-, posed so that the ball can be only printed,

or "it can be supported so that a positive impression can be made in itssurface. 4

In Figure 5 I show a modified form in which the slideway of the frame isdefined by upper rollers '23 and lower rollers 24; at. the to part ofthe frame. V

In' igure 5'. I show a :modification in which the slideway 25 builtright into the frame is the only means for guiding the slide, and'theball instead of rotating in one place'is rotated along a groove orslot 26 down the centre ef'the frame. This form is'usually made of onepiece.

I claim: A ballvmarker comprising a frame with slidewa'ys on the innerfaces at the top, a

slide freely movable in the slideways' and having means for supporting amarking device on its bottom face, and rollers in the frame beneath theslideway, the rollers having' recessed faces and disposed so as to per-'mit' free rotation and to prevent side motion of the ball when the ballis engaged and rotated by the bottom face of the slide.

In testimony that I claim the foregoing, I have hereto set my hand, this31st day of July, 1924:.

GEO. W. DUCHEMIN.
